Haden was recently spotted at an NBA game in a Cleveland Cavaliers shirt, while he is also said he is a big fan of the Cleveland Indians baseball team.
Haden told Cleveland Browns.com: "It's just in my personality. I just like doing stuff.
"I like going to basketball games, I like going to baseball games, Gladiators games, arena football. I'm just interested in sports and anything that has to do with sports.
"Since being in Cleveland, I've seen that everybody else around the city loves the teams, it's just me being myself, and they just love me being out there having fun. I would do this regardless because I just love sports."
The Browns sit in second place in the AFC North with a 4-5 record from their nine games so far.
